IMPROVEMENT IN LIGHTING ATTACHMENTS FOR ALARM-CLOCKS.

Specification forming part of Letters Patent No. [86,317, dated January16, 1877 application filed August 25, 1876. A

Alarm-Clocks; and we do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, which forms part of this specification.

The invention consists in a spring frictionlighter composed of a loopedspring, suitably faced with sand-paper or other friction material, theone end of which is permanently secured, while the other end of saidspring is free to be drawn out to give it .the necessary tension and toeffect its engagement with a retaining-catch till liberated by thealarm.

The invention also consists in a combination, with the spring-frictionlighter, of a ro tating match-holder which is controlled by a spring tohold the match in contact with the spring friction-lighter till thelatter completes its action, and afterward to adjust thelighted matchinto a lighting position with the wick of the lamp to be lit. 1

The invention likewise consistsin a combinatiomwith the-rotatingmatch-holder, of a guard applied to said holder, and serving to supportthe match near its lighting end, and thereby to prevent the match frombeing broken by the rubbing action of the lighter. These severalimprovements not only have their own separate or special advantages.but, when combined, make a lighting attachment for alarm-clocks, whichis cheap, durable, and efficient.

Figures 1 and 2 represent partially sectional front elevations of analarm-clock with our invention applied, and showing the light lighter.Fig. 4 is a side elevation, in detail, of the catch which holds thelighter-spring under tension, and showing said spring as held by thecatch. Fig. 5 is aplan, showing, by

full and dotted lines, the spring-lighter before and after it has beenreleased, and the matchholder and match in corresponding positions.

A is an ordinary clock-movement with alarm combined, B being thewinding-arbor ofthe alarm, and 0 its spring, applied to said arbor. D isthe bell of the alarm, and E its hammer.

Fast to the spring-arbor B of the alarm is a pin or projection, b,which, when the spring Ois released to rotate the arbor B in direc: tionof the arrow'm in Fig. 2, acts upon a triplever, G, to liberate thelighter. When the arbor Bis rotated in the opposite direction, as inwinding up the alarm-spring G, then the pin b passes the leverG withoutoperating it, by reason of the end of the lever on which the pin actsbeing jointed to work free or loose in such direction of the travel ofthe pin, but not in the opposite direction of its travel.

The lever G is connected by a rod, 0, with a lever-catch, H, which holdsthe springlighter under tension. The pin 12, when traveling, asindicated by the arrow 00, (which is when the spring 0 is released towork the alarm,) strikes on the backof the jointed end of the lever G todepress the latter on its jointed end side of the fulcrum, and, throughthe rod 0, to liberate the catch Hfrom its hold on the spring-lighter.

The lighter consists of a looped spring, I, fastened at its one end to apost, (1, and faced, for a portion of its length, with sandpaper orother suitable friction material f, including a tape or web of clothhaving emery or sand on its outer surface. The other end of said spring,or free portion thereof, which has the friction material on its face, ispassed through a slotted or notched guide, 9 g, in the post d, to formthe loop in the spring, and such free portion of the loop made capableof being extended outwardly through the guide 9 g, to give the requiredtension to the spring,

as represented by dotted lines in Fig. 5 of the drawing, and so thatwhen the spring is ,released said extended and friction-faced por- EEIGE.

2 local? tion of the spring is at liberty to fly back through the guide9 g, and in so doing to ignite the match.

The spring friction-lighter, when thus re leased, assumes the positionrepresented for it by full lines in Fig. 5. A hook or projection on thefree end of the spring serves as a handle by which to draw outthespring-lighter, and as a stop to it when released. Said spring-lighteris retained in its drawn-out position at the tension thereby given it,by the engagement of the lever-catch H with a notch, h, in it, and thedisengagement of said catch therewith by the action of the alarm-spring,as hereinbefore described, releases the lighter.

J is the rotating match-holder, erected on top of the clock-case on thefriction side of the spring-lighter, and at aproper distance therefrom,and in such relation therewith as to cause the lighting end dot thematch K, when the holder J has been suitably rotated or turned about itsvertical axis for the purpose. to come in contact with thefriction-surface) of the extended spring-lighter in proximity to theguide gg, as shown by dotted lines in Fig. 5. The match K is thus heldin contact with the friction-surface of the spring-lighter by a spring,I, applied to the rotating matchholder, which spring serves to rotatethe holder after the match has been lit and is liberated from contactwith the spring'lighter, to bring the lit end of the match in contactwith the wick of a lamp, M, as shown in Fig. 2, and by full lines inFig. 5.

To prevent the match slipping from its contact with the extended springfriction-lighter by the action of the spring 1 before said lighter hasbeen released, and to effect an extended and firm yet elastic rubbingaction of said lighter on the match against the resistance of the springI, the guide 9 g, through which the free end of the spring-lighterslides g is arranged so that the portion of the spring lighterpassingoutwardly therethrough forms an acute angle with a line drawnfrom said guide to intersect the axis of the match-holder J, thuscausing the match to rest at its lighting end with a spring-pressure onthe extended light-' er, as shown by dotted lines in Fig. 5. So soon,however, as the spring friction-lighter has been relaxed, as shown byfull lines in Fig. 5, then the match K, which has been lit, is free toclear the lighter, and is adjusted by the rotation of the match-holder Jthrough the action of the spring I, into a position to light the lamp M,as shown by full lines in Figs. 2 and 5, the holder J being arrested bya suitable stop when the match has been thus adjusted.

e To set the lighting devices, it is only necessary to turn back thematch-holder, so as to bring the match into a position approximatingthat shown by dotted lines in Fig. 5, and to draw out the free end ofthe spring-lighter till the notch in in it engages with the levercatchH.

The match K is projected radially through a perforation in the holder J,or two or more matches may be similarly projected through the holder toprovide against failing to obtain alight by reason of a defective match.

To prevent breaking of the match by the action of the lighter, as liableto occur owing to the distance which the forward portion of the matchprojects beyond the rotating holder J, we support the match near itsforward or lighting end by a guard, N, arranged to project from therotating holder, and constructed to receive the match freely through oracross it, and to support the match on its back as it is pressed by thespring l against the spring friction-lighter when the latter is extendedand under tension.

We claim-- 1. Theloopedspring friction-lighter I f, constructed foroperation in connection with the guide g g, and with a catch for holdingsaid lighter when extended, essentially as specified.

2. The combination,with the spring frictionlighter If, of the rotatingmatch-holderJ and its spring l, substantially as described.

3. The combination, with the rotating spring match-holder J, of theguard N, arranged to support the match on its back near its forward endwhen said match is in contact with the friction-lighter, essentially asspecified.
